Which of these classes should he take?

May 2, 2015
By

Jake Humphries writes: I for many years wanted to pursue medicine but after recently completing a master of public health, I caught the statistics bug. I need to complete the usual minimum prerequisites for graduate study in statistics (calculus through multivariable calculus plus linear algebra) but want to take additional math courses as highly competitive […] The post Which of these classes should he take? appeared first on Statistical Modeling,…

Why do we communicate probability calculations so poorly, even when we know how to do it better?

April 13, 2015
By

Haynes Goddard writes: I thought to do some reading in psychology on why Bayesian probability seems so counterintuitive, and making it difficult for many to learn and apply. Indeed, that is the finding of considerable research in psychology. It turns out that it is counterintuitive because of the way it is presented, following no doubt […] The post Why do we communicate probability calculations so poorly, even when we know…

How can teachers of (large) online classes use text data from online learners?

Dustin Tingley sends along a recent paper (coauthored with Justin Reich, Jetson Leder-Luis, Margaret Roberts, and Brandon Stewart), which begins: Dealing with the vast quantities of text that students generate in a Massive Open Online Course (MOOC) is a daunting challenge. Computational tools are needed to help instructional teams uncover themes and patterns as MOOC […] The post How can teachers of (large) online classes use text data from online…

Harvey Motulsky writes: Every year at passover, I struggle to peel two dozen hard boiled eggs and search the web to see if there isn’t a trick to do it better. But all the hits say the same thing: put the eggs in cold water, then bring to a boil. But this guy [J.

Learning to teach statistics, in a MOOC

I am participating in a MOOC, Teaching statistics through data investigations. A MOOC is a fancy name for an online, free, correspondence course.  The letters stand for Massive Open Online Course. I decided to enrol for several reasons. First I … Continue reading →

Time-release pedagogy??

Mark Palko points to this report and writes: Putting aside my concerns with the “additional years of learning” metric (and I have a lot of them), I have the feeling that there’s something strange here or i’m missing something obvious. That jump from 3-year impact to 4-year seems excessive. The press release links to a […] The post Time-release pedagogy?? appeared first on Statistical Modeling, Causal Inference, and Social Science.

Regression: What’s it all about? [Bayesian and otherwise]

March 29, 2015
By

Regression: What’s it all about? Regression plays three different roles in applied statistics: 1. A specification of the conditional expectation of y given x; 2. A generative model of the world; 3. A method for adjusting data to generalize from sample to population, or to perform causal inferences. We could also include prediction, but I […] The post Regression: What’s it all about?

Define first, prove later

March 25, 2015
By

This post by John Cook features a quote form a book “Calculus on Manifolds,” by Michael Spivak which I think was the textbook for a course I took in college where we learned how to prove Stokes’s theorem, which is something in multivariable calculus involving the divergence and that thing that you get where you […] The post Define first, prove later appeared first on Statistical Modeling, Causal Inference, and…

New time unit needed!

March 18, 2015
By

We need a time unit that’s bigger than a minute but smaller than an hour. I thought of it when writing this comment in which I referred to “2100 valuable minutes of classroom time” during the semester (that’s 75 minutes per class, twice a week, for 14 weeks). A minute of class time is pretty […] The post New time unit needed! appeared first on Statistical Modeling, Causal Inference, and…

Stock-and-flow and other concepts that are important in statistical modeling but typically don’t get taught to statisticians

March 12, 2015
By

Bill Harris writes: You’ve written about causality somewhat often, and you, along with perhaps everyone who has done anything with statistics, have written that “correlation is not causation.” When you say that correlation is not causation, you seem to be pointing out cases where correlation exists but causality does not. While that’s important, there’s another […] The post Stock-and-flow and other concepts that are important in statistical modeling but typically…
